This is the second solution to to reverse each word in the given input line of strings. This program uses the core logic to reverse each string.

import java.util.Arrays;
import java.util.List;
import java.util.Scanner;

public class Reversingeachword {

	public static void main(String[] args) {
		// TODO Auto-generated method stub

		Scanner inpStr=new Scanner(System.in);
		System.out.println("Enter an input sentence");
		String inpLine=inpStr.nextLine();
		String resultStr ="";

		//Split the input sentence into list of words with space as delimiter
		List<String> words=Arrays.asList(inpLine.split("\\s"));

		// Pass each word to the reverse function which returns the reversed string value
		for (int i=0;i<words.size();i++) {
			resultStr = resultStr + ReversingEachWord(words.get(i))+" ";
		}
		inpStr.close();
		System.out.println("The output sentence after reversing each word is below");
		System.out.println(resultStr);
	}

	private static String ReversingEachWord(String strVar) {

		// Using basic logic of storing characters in the reverse order
		String strRev= "";
		for (int i=strVar.length()-1;i>=0;i--)
			strRev = strRev + strVar.charAt(i);
		return strRev;
	}
}
